Liquid exhaust pipe purifier

Abstract

The invention relates to a liquid exhaust pipe purifier. A shell is divided by an insulating partition plate perpendicular to the axis of the shell into two closed expansion cavities. An elastic net cylinder parallel to and coaxial with the shell is installed in each expansion cavity. Closed purification ring cylinders defined by the shell, the partition plate and the net cylinders are filled with purification liquid. The purification ring cylinders are communicated with elastic cooling boxes, metal gas guide pipes are fixed to the gas inflow end and the gas outflow end respectively, a metal ventilation pipe perpendicularly penetrating through the partition plate is fixed to the partition plate, the metal gas guide pipes and the metal ventilation pipe are electrically connected with the positive electrode of a high-voltage power source, and the shell is electrically connected with the negative electrode of the high-voltage power source. The purifier is low in manufacturing cost and small in size, harmful gas and impurities in tail gas can be efficiently purified, the auxiliary silencing function is achieved, the temperature of the tail gas can be reduced, and the service life of an exhaust pipe is prolonged.

Description

technical field [0001] The invention relates to an automobile exhaust pipe fitting, in particular to a purifier. Background technique [0002] The purification devices commonly used in automobile exhaust systems mainly include three-way catalytic converters. Its carrier part is a porous ceramic material, and precious metals such as platinum, rhodium, and palladium are coated on its surface; CO, HC and NO in exhaust gas X and other harmful gases are decomposed into CO 2 、H 2 O, N 2 and O 2 and other harmless gases and discharged into the air; this kind of purifier has the following disadvantages: First, it needs to ensure a certain active temperature during use; when the temperature is too low, the catalytic efficiency drops sharply, and when the temperature is too high, it is easy to cause The aging of the catalyst is aggravated, which shortens the service life of the purifier; second, the cost of this purifier is relatively high; third, since the active temperature is ...
